Are Your Sunglasses Protecting Your Eyes from UV Rays?

by ArticlesBlog

As the days get sunnier and warmer, many of us reach for our favorite sunglasses, not just as a fashion statement but as a way to protect our eyes. While sunglasses can be stylish, their primary role is far more significant: shielding your eyes from the harmful effects of ultraviolet (UV) rays. At Bissell Eye Care we’re committed to educating our patients about eye health and want to share how to choose the right pair of sunglasses for optimal protection.

Why UV Protection is important.

The sun emits UV radiation, which is categorized into three types: UVA, UVB, and UVC. While the Earth’s atmosphere blocks most UVC rays, UVA and UVB can reach us and pose risks to our health. Prolonged exposure to these rays can cause various eye problems, such as:

  • Cataracts: UV exposure can accelerate the development of cataracts, a clouding of the eye’s lens that can lead to vision impairment.
  • Macular Degeneration: UV rays can damage the retina, particularly the macula, leading to age-related macular degeneration (AMD), a major cause of vision loss in older adults.
  • Photokeratitis: This is essentially a sunburn of the eye, which can cause pain, redness, and temporary vision loss.
  • Pterygium: A growth on the white part of the eye that can extend to the cornea and affect vision.
  • Skin Cancer: The delicate skin around the eyes is also susceptible to UV-induced skin cancers, such as basal cell carcinoma.

How to Choose the Right Sunglasses

When selecting sunglasses, it’s important to consider both style and functionality. Look for UV protection labels to ensure that the sunglasses offer 100% UV protection. This might be labeled as “UV400,” meaning they block all UVA and UVB rays. Be wary of fashion sunglasses that may not provide adequate protection.

Choose the Right Lens Color:

  • Gray: Reduces overall brightness without distorting colors, suitable for most activities.
  • Brown/Amber: Enhances contrast and depth perception, ideal for driving and outdoor sports.
  • Green: Reduces glare and enhances contrast, maintaining natural color balance.
  • Yellow/Gold: Improves visibility in low-light conditions but can alter color perception.

Larger frames provide more coverage and better protection from peripheral UV rays. Wraparound styles are excellent for blocking light from the sides.

Polarized lenses reduce glare from reflective surfaces like water and pavement, enhancing comfort and visibility, especially during activities like driving or fishing. A mirror coating reflects more light and is beneficial in extremely bright conditions. Anti-scratch and anti-reflective coatings: prolong the life of your sunglasses and improve visual comfort.

Special Considerations for Different Activities

  • For Outdoor Sports: Opt for polycarbonate lenses and wraparound frames for durability and protection.
  • For Driving: Polarized lenses can significantly reduce glare from the road and other vehicles.
  • For Everyday Use: A versatile pair with 100% UV protection and a comfortable fit is ideal for daily wear.

Choosing Sunglasses

Tips for Choosing Sunglasses

by ArticlesBlog

Available in many shapes and styles, sunglasses are more than fashion accessories – they are important tools to protect your eyes from ultraviolet (UV) rays, the radiation energy produced by the sun. UV rays are a contributing factor in developing cataracts. Did you know two types of radiation – UVA and UVB rays occur with exposure to sunlight? Ultraviolet radiation from the sun can cause cumulative damage to your eyes as you age, but you can protect your vision by wearing sunglasses every day.

Polarized sunglass lenses reduce light glare and eyestrain. Because of this, they improve vision and safety in the sun. Polarization itself does not provide UV protection. Instead, it provides a better visual experience for certain activities like driving, boating, or golfing. People who use polarized sunglasses often say they are less tired than usual after hours of battling sun glare. There are polarized lenses made with a UV-blocking substance. Check the label of polarized sunglasses to make sure they provide maximum UV protection.

On polarized sunglasses, the filter creates vertical openings for light. Only light rays that approach your eyes vertically can fit through those openings. The lenses block all the horizontal light waves bouncing off a smooth pond or a shiny car hood, for instance. As a result of this filtering, the image you see with polarized lenses is a bit darker than usual. But objects look crisper and clearer with polarized lenses, and details are easier to see.

UV Blocking and Polarization Are Not the Same

Since UV light carries more energy than visible light, it can do greater damage to our eyes. As we age, the damage simply has more time to accumulate: a cataract, (cloudiness of the lens) for example, is believed to be caused by many years of exposure to bright sunlight. Choose sunglasses with 100% UV blockage. Since you can’t tell by looking at the glasses for UV blockage. Just because glasses have a darker tint it not an indication of protection, you should always look at the label.

Tips for Choosing the Best Sunglasses

According to the American Academy of Ophthalmology (AAO), the best sunglasses offer:

  • 100% UV protection
  • High optical quality (lenses are free of manufacturing defects like bubbles or waves that could bother your eyes
  • Scratch-resistant lenses
  • A larger frame offers more coverage of eye area

A person’s lifestyle can affect their choices in sunglasses. Special features in sunglasses can include:

  • Mirror coatings. These thin layers of various metallic coatings can reduce the amount of visible light entering the eyes. They are popular in high-glare environments and when combined with the wraparound feature, they can even provide added protection to the skin surrounding the eye area. UV protection, however, is not guaranteed.
  • Gradient. These lenses are permanently shaded from top to bottom or from top and bottom toward the middle.
  • Impact resistant. While all sunglasses must meet minimum FDA standards regarding impact resistance, no lens is truly shatterproof. Plastic lenses are less likely to shatter upon impact than glass lenses. And, polycarbonate plastic, used in many sports sunglasses, is even more impact resistant than regular plastic but scratches easily. If you buy polycarbonate lenses, look for ones /with scratch-resistant coatings.

Protection from the ultraviolet rays from the sun can occur by wearing sunglasses and a wide-brimmed hat. These two things can significantly reduce eye exposure to UVB radiation. Although cataracts are not completely preventable, their occurrence can be delayed. Smoking, avoiding excess amounts of alcohol, eating plenty of fresh fruits and vegetables may delay the formation of cataracts.

Keep in mind that if your sunglasses are labeled as blocking the sun’s harmful ultraviolet (UV) rays, it does not mean they are polarized too. Polarized lenses will have a label saying so.

THE LINK BETWEEN SUNGLASSES AND CATARACTS

by ArticlesBlog

June is National Cataract Awareness Month, and UV rays are a significant risk factor for the eye disorder. The proper sunglasses can help protect you. As we get older, our eyes undergo physiological changes that can cause vision problems.

Ultraviolet light from the sun carries two types of radiation, UVA, and UVB rays. Ultraviolet radiation from the sun can cause cumulative damage to your eyes as you age, but you can protect your vision by wearing sunglasses every day.

Since UV light carries more energy than visible light, it can do greater damage to our eyes. As we age, the damage simply has more time to accumulate: a cataract, (cloudiness of the lens) for example, is believed to be caused by many years of exposure to bright sunlight. Choose sunglasses with 100% UV blockage. Since you can’t tell by looking at the glasses the UV blockage – darker tint is not an indication, you should always look at the label.

Sunglasses help to protect your eyes against UVB rays that cause cataracts. A cataract is the clouding of the normally clear lens of your eye. Seeing with cataracts is like looking through a frosty or fogged window. Cataract sufferers may also experience sensitivity to light, see “halos” around lights, notice fading or yellowing colors or have double vision in one eye.

Tips for Choosing the Best Sunglasses

According to the American Academy of Ophthalmology (AAO), the best sunglasses offer:

  • 100% UV protection
  • High optical quality (lenses are free of manufacturing defects like bubbles or waves that could bother your eyes
  • Scratch-resistant lenses
  • A larger frame offers more coverage of eye area

Most cataracts develop slowly and don’t disturb your eyesight early on. But with time, cataracts will eventually interfere with your vision and your eye doctor will help you decide if surgery is right for you.

Protection from the ultraviolet rays from the sun can occur by wearing sunglasses and a wide-brimmed hat. These two things can significantly reduce eye exposure to UVB radiation. Although cataracts are not completely preventable, their occurrence can be delayed. Smoking, avoiding excess amounts of alcohol, eating plenty of fresh fruits and vegetables may delay the formation of cataracts.

When to see a doctor…Make an appointment for an eye exam if you notice any changes in your vision such as double vision or blurriness, see your doctor right away. Talk with your eye doctor about whether surgery is right for you.

SUMMER ~ SUNSCREEN ~ SUNGLASSES

by ArticlesBlog

As we roll into summer, sunscreen and sunglasses are a winning combination. Sunglasses are an easy solution that makes life more comfortable when outdoors, while also providing critical protection from the sun’s damaging ultraviolet (UV) rays. But…all sunglasses don’t provide the protection you need to protect your eyes.

Long-term exposure to UV rays can damage the eye’s surface as well as its internal structures. This damage can sometimes lead to eye conditions such as cataracts (clouding of the lens) and macular degeneration (breakdown of the macula).

Did you know that glaucoma can make eyes highly sensitive to light and glare, with some glaucoma medications exacerbating the problem even further?

A brimmed hat whenever you’re in the sun long enough to get a suntan or a sunburn, is recommended along with sunglasses to help protect your eyes from the sun. If you have blue, green, or gray eyes, you may have noticed yourself squinting into the sunlight more than your brown-eyed counterparts. Light sensitivity — typically affects people with light eyes because they have less pigmentation in multiple layers of the eye than those with darker eyes.

Here are some things to keep in mind when shopping for sunglasses:

  • Look for UV protection.
  • Don’t be deceived by color or cost. The ability to block UV light is not dependent on the darkness of the lens or the price tag. Always choose sunglasses that are labeled as blocking 99-100% of UV rays.
  • Polarized lenses block out not only direct rays from the sun but also light reflecting off surfaces such as water, snow or reflective metals. Polarization is unrelated to UV protection, so you still need to ensure UV absorption of the lenses.
  • Blue light blocking.
  • Photo Chromic lenses adjust with the light and can be a compromise from buying dark lenses allowing you to see well in different level of brightness.
  • Wrap around frames and lenses add extra coverage and help to block out the light from all angles providing the best protection for your eyes. Some studies have shown that enough UV rays enter around standard sunglass frames to reduce the protective benefits of the lenses.
  • Check lenses for quality. Look for a uniform tint, not darker in one area than in another.

Special features in sunglasses can include:

Mirror coatings. These thin layers of various metallic coatings can reduce the amount of visible light entering the eyes. They are popular in high-glare environments and when combined with the wraparound feature, they can even provide added protection to the skin surrounding the eye area. UV protection, however, is not guaranteed.

Gradient. These lenses are permanently shaded from top to bottom or from top and bottom toward the middle.

Impact resistant. While all sunglasses must meet minimum FDA standards regarding impact resistance, no lens is truly shatterproof. Plastic lenses are less likely to shatter upon impact than glass lenses. And, polycarbonate plastic, used in many sports sunglasses, is even more impact resistant than regular plastic, but scratches easily. If you buy polycarbonate lenses, look for ones with scratch-resistant coatings.

Buying a pair of sunglasses that offer little more than looks and some shade for your eyes can not only fail you at blocking out the proper amount of sunlight, but they can also cause short term and long term damage to your eyes. Bissell Eye Care carries a full line of RXable (either prescription or nonprescription) sunglasses in a variety of styles and colors.

Wear sunglasses whenever you are outdoors, whether you are working, driving, participating in sports, taking a walk, running errands or doing anything in the sun. Remember this summer as you enjoy the nice weather it is important to protect not only your skin but also your eyes. If you have any questions about proper eye protection, stop in and see us so we can help you ensure you enjoy your summer!

Eye-Safety-in-Sports

WATCH THE BALL

by ArticlesBlog

Eye-Safety-in-SportsWith the school buses back on the road, it is easy to see that school is back in session. If your children are like many, this also means that fall sports have started back up again. Players suit up with the proper uniform, but having the right eyewear will also help your kids keep their eye on the ball, resulting in a great fall sports season.

From soccer, football, lacrosse, fall baseball and other contact sports, each year 42,000 athletes suffer eye injuries that result in a visit to their eye doctor or emergency room. Many of these injuries are preventable with the proper eye protection.

Many eye injuries from contact sports occur when impact from a ball or another player can lead to several different types of injuries. The injuries most commonly seen are corneal abrasions, fracturing of the orbital bone (eye socket), or swollen and detached retinas.

While eye injuries are more common in contact sports, they are not limited to these activities. Many students suffer damage to their eyes from not having the proper eye protection from the sun. Activities such as marching band, cheerleading, or even running cross country, tend to have the students outside in the sun for prolonged periods of time. The UV rays of the sun can sun burn an eye much like it can skin. This can result in a range of problems from discomfort and dry eye, to permanent loss of sight in extreme cases.

Now the good news! In most cases, the proper eye protection can prevent your children from having to endure these injuries. Spectators should also take precautions, especially with using sunglasses with UV protection.

Polycarbonate safety goggles offer great protection from injuries in sports such as basketball, racquetball, tennis and soccer. When looking for goggles, be sure they fit properly and that they are labeled ASTM F803 approved. These are the goggles that have been tested and are approved for impact sports.

If your child plays hockey or baseball, a helmet with a protective face shield will offer the most protection from a wild pitch, a flying puck or even a stick. Make sure the helmet fits properly and does not move around on their head or fall off. It is also important to have the shield fit snugly to your child’s face and chin.

For activities such as marching band, cheerleading, or cross country, be sure that your children are sporting a pair of sunglasses that have UV protection. Because these activities are not considered high impact contact sports, regular sunglasses with UV protection will help to prevent damage from the sun.

As your kids suit up this fall, be sure that their uniform includes the proper eye protection. Wishing you all a successful fall sporting season!
